ABSTRACT:
A weft feeder for gripper or projectile looms comprising a body housing a motor, a drum idly mounted on the motor shaft and held stationary around which a winding arm rotated by the motor winds up a weft yarn reserve, a bracket positioned alongside the drum and carrying sensors to detect and control the yarn reserve as well as a brake to stop the yarn against the end surface of the drum, and three compressed air devices acting on the yarn to automatically restore the continuity of the weft yarn from the feed spool to the loom is disclosed. The first device is positioned at the inlet of the weft feeder to withdraw therefrom broken yarn and introduce therein new yarn fed by the spool. The second device is positioned adjacent to the weft feeder drum to receive the new yarn fed by the first device and by the winding arm to send it to a fixed point. The third device consists of at least a suction nozzle mounted, downstream of the brake, at the end of the weft feeder bracket positioned alongside the drum. The bracket is adapted to move the brake and the suction nozzle from their usual position centered on the weft feeder axis, to a position in which the inlet of the suction nozzle coincides with the fixed point.
